דברי הימים א, פרק ה׳, פסוק ל״ד

The genealogy of the priesthood reaches a major turning point in history. The arrival of Zadok marks a central milestone, as he was the very first High Priest to serve in the Temple.

From Zadok onward, a firm tradition was established. The High Priesthood was passed down continuously from father to son for twelve consecutive generations [מצודת דוד].
